Abstract:
One or more implementations of a multi-layered bag with reinforced seals include an outer layer or bag and an inner layer or bag positioned within the outer layer or bag. The multi-layered bag further includes a draw tape positioned near the opening of the multi-layered bag. The draw tape can allow a user to at least partially close the multi-layered bag by drawing the layers of the bag together. The multi-layered bag further includes one or more tape seals that bond the draw tape to layers of the bag. The tape seals can be reinforced and include at least seven plies bonded together. One or more implementations further include methods of forming multi-layered bags with reinforced seals.
Abstract:
Thermoplastic bags include laminates with bonded protrusions. More specifically, one or more implementations include a first thermoplastic film with a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the first thermoplastic film and second thermoplastic film bonded to the protrusions (e.g., raised rib-like elements or troughs between the raised rib-like elements) of the first thermoplastic film. By bonding a second thermoplastic film to the protrusions of the first thermoplastic film, the resulting laminate has an increased effective gauge or loft. In one or more implementations the second thermoplastic film is a flat film. In alternative implementations, the second thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the second thermoplastic film and protrusions of the first thermoplastic film are bonded to protrusions of the second thermoplastic film.
